The invention further consists in the features of construction and the combination of parts hereinafter described and claimed.

In the drawings:

Figure 1 is a plan view of the device;

'Fig'. 2, a vertical section through the device;

F ig. 3, a side elevation of the device, with the dial and cap ring imsection. u

F ig.' 4 is a plan view showing'a portion of a dial. Fig. 5 is a-se'ct1onal view taken on line 1-1 of Fig. 4.

In the art to which the present invention, l relates, and particularly in connection with automobiles, it is desirable to have somo outward means by which the driver can determine thc amount of gasolene within the tank at a glance, thus dispensing with the necessity of removing the covering of the tank zllld using the ordinary measuring stick.

. edge of a flange 1T extending'fromv- And it is to produce a simple. mechanism for enabling a determination of the amount of liquid b means located extcriorly of the tank that t 1e present invention has been designed.

Referring now to the drawings, the structure'comprises a frame or mounting 4, which is formed of a single piece of metal, and which, in the construction shown, is bent at cach end to produce what may be termed an upper lug or flange 5 and a lower lug or Harige 6. Secured to the lug 5 in a suitable manner 1s a dial 7, having thereon various scale' marks 8, which designate a certain4 amount of liquid. v ,l -l i f4; j

and as the float rises and falls, it obviously rocks the 'plate 1S about its pivotal center.

In order to prevent leakage about the point where the rod 13 passes through the dial, I provide a washer 23 of felt or other suitable substance, and also provide a spring 24 about the rod 13 for maintaining this washer in osition.

T he ben ing of the plate 18 to produce the ange 17 forms shoulders 25 at each end of 'the ilange. These shoulders coperate with the sides 26 at the' end of the supporting` frame 4, to form a stop limiting the movement of the plate 18 in either direction. This is to insure the rack and pinion beiner maintained in continual engagement, so tdiat the pointer or indicator 14 is always under the direct control of the {ioat member.

From the foregoing it will be apparent that the device of the present invention is extremely simple in construction and consequently cheap of manufacture, and that it contains no involved nor intricate parts that would be liable to become disarranged in ordinary use.

I claim:

1. In a gasolene gage, in combination with a portion of a gasolene tank, a circular dial resting directl on said poi-tion, a oke comprising a longitudinal reinforced ritil and two end walls, one of said end walls being riveted to said dial, a rotary shaft supported between the end walls of the yoke and projecting beyond the dial, a gear rigidly secured to the outer end of the shaft rejecting through one end wall, a toothed) segment pivota 1y mounted onv the outer surface of the yoke and in engagement with the ear, and a float detachably secured to said toothed se ment in such manner that the distance o the lower end of the tioat from the pivot of the segment may be varied.

2. In a asolene gage,.in combination with a portion of a gasolene tank, a dial mounted directly on said portion, a yoke riveted to said dial at diametrically opposite points with respect to the center portion of the same, said yoke comprising a longitudinal reinforced rib and end walls, a rotary shaft mounted in the end walls and projecting through both of the same and through the dial, a gear rigidly mounted on said rotary shaft at the end projecting through one end wall, a toothed segment mounted pivotally on the longitudinal portion of the yoke at the surface directed away from the shaft. a float support adjustably mounted on the pivotal toothed segment at the outer surface of the same, and a {ioat connected with said support,

3. In Ia gasolene gage, in combination with a flanged portion of a gasoiene tank, a dial non' rotatably secured to said flanged portion, a yoke riveted to the lower face of the dial and comprising a longitudinal portion and two end walls, a shaft rotatably supported in said end walls and projecting through said end walls and dial, a tioat con trolled segment pivotally mounted on the longitudinal portion of the yoke, a gear on the shaft irtrengagement with the segment, a washer in engagement with the lower face of the upper end wall of the yoke and surrounding the rotary shaft, and a spring resting on the other end wall and pressing against said shaft for maintaining said washer yieldingly in iiuid tight engagement with the other end wall.

4. In a gasolene gage, the combination with a tank, a dial, mounted on said tank, a yoke bent to form two end walls, one of said end walls being secured to said dial, a rotary shaft supported between the end walls of the yoke, and projecting beyond the dial, a gear rigidly secured to the outer end of the shaft, a toothed segment pivotally mounted on the outer surface of the yoke and in engagement with said gear, and a fioat connected to said toothed segment, whereby movement of said float rotates said shaft.

5.111 a gasolene gage, in combination with a portion of a tank, a circular dial, a lip punched from the plane of the dial and projecting downwardly, said circular portion of the tank being lprovided with a flange which has a recess adapted to receive said lip, a yoke riveted to said dial, an indicator shaft supported by the yoke, a gear on Said indicator shaft,'and a float controlled sector pivotally mounted on the yoke in engagement with said gear.
